Note 11 — Chapter VI · THE STUDY OF NATURE. FUNDAMENTAL POSITIONS.

On this point, the Stoics were not altogether agreed. Some (not all, as Plut. Pl. Phil. iv. 21, 5, asserts) made the brain the seat of the soul, in proof of which they appealed to the story of the birth of Pallas. Sext. Math. ix. 119; Diog. in Phædr. Fragm. De Nat. De. col. 6. Conf. Krische, Forschungen, i. 488, and Chrysipp. in Galen, l.c. iii. 8, p. 349. It appears, however, from Galen, l.c. i. 6, ii. 2 and 5, iii. 1, pp. 185, 214, 241, 287, Tertull. De An. c. 15, that the most distinguished Stoics—Zeno, Chrysippus, Diogenes, and Apollodorus—decided in favour of the heart. The chief proof is, that the voice does not come from the hollow of the skull, but from the breast. Chrysippus was aware of the weakness of this proof, but still did not shrink from using it. Galen, l.c. p. 254, 261. At the same time, he also appealed to the fact (ii. 7, 268; iii. 1, 290, c. 5, 321, c. 7, 335, 343; iv. 1, 362) that, by universal assent, supported by numerous passages from the poets, the motions of the will and the feelings proceed from the heart. ↑
